WASHINGTON -- A bomb threat involving gay and lesbian advocacy groups in the District of Columbia led to the evacuation of two buildings.

Two buildings in D.C.'s Dupont Circle neighborhood were reportedly evacuated while D.C. police investigated the threat. One building, at 1640 Rhode Island Ave. NW, houses the group Human Rights Campaign. The other, at 1325 Massachusetts Ave. NW, houses a number of LGBT advocacy groups, as well as some prominent unions and trade groups.

Fred Sainz, vice president for communications for the Human Rights Campaign, told The Huffington Post that earlier today, a "call of unknown origin" was placed to a California police department, warning of an attack on "a national gay rights organization."

D.C. police contacted Human Rights Campaign and groups in the building at 1325 Massachusetts Ave. NW, asking them to leave their offices.

Metro Weekly tweeted just before 1 p.m. that HRC staff had been given the "all clear" to return to their offices:

At 12:50p, DC police gave the "all clear" for staff to return to their offices following an unspecified bomb threat.

Calls to groups located in the other evacuated building were not answered, nor were calls to the D.C. police.

Twitter user @DJMaskell posted a photo from the scene.
